Grey Water Re-use

Greywater is waste water from washing machines, kitchens, laundry tubs, showers, hand basins and baths. It does not include waste water from toilets, urinals or bidets.

Reusing greywater can replace the need to use drinking water for watering gardens or lawns and, if treated appropriately, can be used in toilets and washing machines. By using greywater for watering gardens and lawns, a household has the potential to save between 50,000 and 100,000 litres of drinking water a year.

These new regulations mean that council approval is no longer required for greywater diversions to be installed in homes, provided certain conditions are met. The guidelines relate to single, detached households only and do not include premises comprising of more than one dwelling.
